Matthias Schleiden,a German botanist,examined a large number of plants and observed that all plants are composed of different kinds of cells which form the tissues of the plant. In $1838$,he reported that all plants are composed of cells. Theodor Schwann,a British zoologist,reported in $1839$ that animal cells had a thin outer layer which is today known as the 'plasma membrane'. Thus,the cell theory was formulated in the year $1838-1839$.
